Consider the four circuited shown in the figure, each consisting of a battry, a switch, a light bulb a resistor, and eutger a capacitory or an iductor. Assume the capacitor has a large capacitorand the inductor has a large inductance but no resitance. The light bulb has high efficiency. glowing whenever it carries electric current. (i) Describe what the light bulb does in each of each of curcuits (a) through (d) after the switch is thrown closed. (ii) Describe what the light bulb does in each of circuits (a) through (d) when, having been closed for a long time interval, the switch is opened.

A technician wraps wire around a tube of length 4 π2 cm having a diameter of 8.00 cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 1000turns of wire. If the current in this solenoid increases at the rate of 4.00 A/s. the inductance of this solenoid is
